System and method for authenticating devices in distributed environment
Methods, systems, and devices for providing for trust in a distributed environment are disclosed. In a distributed environment, various devices may be remote to one another and may interact with one another via one or more operable connections. Through the operable connections, various communications may be exchanged. However, the operable connections may not natively support authentication of any particular device in the distributed system. Consequently, entities in the distributed system may not intrinsically trust that the communications received through the distributed environment are authentic. The entities of the system may mutually authenticate one another prior to trusting communications from the other entities. For example, in a scenario where a client wishes to access data hosted by a data source, the client and data source may go through a process of mutually authenticating one another. By doing so, a trusted environment may be established. |

Message broker consumer group versioning
In an example embodiment a mechanism for consumer group versioning is introduced. Here, each application runtime provides a version for any consumer group during its deployment and keeps increasing the version whenever there is an enhancement or bug fix. Thus, both the application and the consumer group will have a version. Once it is recognized that a consumer group assigned to partitions in a topic has an outdated consumer group version number (i.e., a consumer group with the same name/application but a later consumer group version number has been registered with the message broker), the old consumer group is disconnected immediately. This allows the message broker to immediately assign partitions to the consumers in the newer consumer group, thus avoiding the aforementioned delays and associated technical problems. |

Specifying routes to enable Layer-2 mobility in hybrid-cloud environments
Techniques for using more-specific routing to perform scalable Layer-2 (L2) stretching of subnets across hybrid-cloud environments. Routing tables in a public cloud may allow for routes that are more specific than the default local route, and the more-specific routes may be used to send all traffic to a dedicated, cloud router.

The next hop for the more-specific routes point to the cloud router which is capable of doing host routing and segmentation extension. Thus, traffic originating from endpoints in a VPC is routed to the cloud router, and the cloud router determines whether the traffic is to be re-routed back to a destination endpoint in the VPC (or another cloud location), or sent to a destination endpoint residing in the on-premises site. |

Packet processing method and apparatus, network device, and storage medium
An identifier can indicate whether local protection is allowed is added to a packet. In a process in which a packet that carries a protection flag is transmitted along a primary path, if a node along the path determines that the primary path is faulty, but the protection flag indicates that local switching to a protection path is not allowed, the node along the path does not perform local protection, so that the packet is not switched by the node along the path to the protection path. This prevents the packet from passing through a protection path with the node along the path as an ingress when the primary path is faulty, helps traffic on the primary path to be switched to an end-to-end protection path in time, and helps a packet sending side to switch the traffic on the primary path to the end-to-end protection path in time. |
